Observed incident recordDetected by RELIASTRA probes

Official status page failure window - SendGrid

Incident 090f9d24-a999-4968-ba3f-cca7154d15e8 - endpoint status.sendgrid.com, measured from us-east. Confirming rule: 2 consecutive failed observations counted 2 of them.

Observed window

Every timestamp is a stored field of this record, printed in UTC. The window begins at the first failure the rule counted and ends, for a resolved record, at the observation run whose consecutive successes closed it.

Opened: 26 Oct 2026 17:02:27 UTC
Confirmed: 26 Oct 2026 17:09:43 UTC - the run that made the failure count reach the threshold; this record did not exist before it
Recovered: 26 Oct 2026 17:18:14 UTC
Duration: 15m (from the stored window)

What was measured

The record is a summary of an observation run set. The referenced observation ids resolve to stored probe entries inside the retention window; the detector keeps no second, narrative version of them.

Endpoint observed: Official status page - https://status.sendgrid.com
Measured from: us-east - the only observation region named in this record; nothing about other regions is claimed or inferred
Failed observations: 2, consecutive through the trigger set
Failure shape: mixed failure modes - status codes recorded: 302
Observation references: first 1dd999a9-777a-4ded-99c3-e0db22f01ddb last d5655d13-5164-4a0a-906f-db1b7d43cbc9

The claim, in full

Between 2026-10-26T17:02:27.111701+00:00 and 2026-10-26T17:09:43.411542+00:00, RELIASTRA probes in us-east recorded 2 consecutive failed observations against https://status.sendgrid.com (the observed SendGrid target). Failure class: mixed; observed status: 302. This record describes the observed endpoint only and is not a statement about the vendor's services as a whole. That is all of it. Nothing about the vendor as a whole, nothing about other regions, nothing about your requests - the record you are reading is the measurement, not a narration of it.

Evidence artifact

A frozen, hashed document of this record's window: the claim, the detection rule, and every observation row it rests on. Deterministic, reproducible from stored data, immutable once written.

Artifact: /api/v1/public/incidents/090f9d24-a999-4968-ba3f-cca7154d15e8/evidence - JSON, served byte-for-byte as stored
Content hash: sha256: 36e54e226356a11fcfec77efde88d64cd8e8f1be17bb8ac08edf078774de97aa
Freeze: version 2, taken while the incident was resolved (26 Oct 2026 17:24:16 UTC); later freezes supersede, never edit, and each stays at its own versioned URL
Coverage: 6 observations in the window
Verification: Remove the "verification" key from the document, re-serialise with sorted keys and compact separators, and SHA-256 the UTF-8 bytes: the digest must equal the hash above. The recipe ships inside every artifact.

What this record does not establish

The boundaries are part of the record, not a disclaimer under it.

Causation: Not established. A 5xx can be the vendor, a shared middle path, or the probe's own egress - the record reports what came back, not why.
Vendor acknowledgement: SendGrid may have recorded this window differently, later, or not at all. RELIASTRA does not ingest vendor-reported status, so no reconciliation is offered either way.
Global reach: This window is named for us-east. A record from one observation region never settles the question in another.
Customer impact: Whether your requests were affected is your measurement to make - this record carries only RELIASTRA's own probes.
